Dual Display Mobile Terminal Real-Time Composition Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In existing photographing methods, the composition can only be determined by the photographer, leading to unsatisfactory photos for the photographed person, as they cannot see the composition mode or photographing effect in real time.
Innovation Solution
A mobile terminal with dual displays is used, where a preview image is shown on one screen and composition reference information is displayed on the other, allowing the photographed person to select and adjust their position according to the composition information in real time before taking the photo.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the photographer determines the composition using traditional methods, then the photographing process is simple, but the photographed person cannot see the composition mode or photographing effect in real time and may be unsatisfied
Solution Approach 1:
The patent introduces a second display screen that provides a third-dimensional viewing angle for the photographed person. This additional display dimension allows simultaneous presentation of preview images and composition reference information to different users (photographer and photographed person), resolving the information asymmetry without significantly increasing overall system complexity.
Solution Approach 2:
The second display screen acts as an intermediary device that bridges the information gap between the photographer's view and the photographed person's needs. It mediates the composition process by displaying both the preview image and composition reference information, enabling the photographed person to understand and adjust their positioning in real time.
2Ease of operation
If composition reference information is displayed to the photographed person, then real-time adjustment and satisfaction are improved, but the device complexity increases
Solution Approach 1:
The second display screen serves multiple functions: displaying preview images, showing composition reference information, and providing real-time feedback to the photographed person. This multi-functionality allows a single additional component to address multiple needs, improving ease of operation while minimizing the increase in device complexity.
Solution Approach 2:
The system enables the photographed person to independently view composition reference information and adjust their own positioning without requiring constant guidance from the photographer. This self-service capability simplifies the interaction process and reduces the operational burden on the photographer.
3Loss of information
If traditional single display method is used, then device complexity is low, but the photographed person cannot preview the photographing effect and composition mode
Solution Approach 1:
The patent introduces a second display screen that provides a third-dimensional viewing angle for the photographed person. This additional display dimension allows simultaneous presentation of preview images and composition reference information to different users (photographer and photographed person), resolving the information asymmetry without significantly increasing overall system complexity.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This approach enables the photographed person to select a composition that satisfies them, resulting in more aesthetically pleasing photos by allowing real-time adjustment and preview of the composition reference information.

AI summary
A photographing method and a mobile terminal are provided, which are related to communication technologies. The photographing method includes: receiving a photographing function start instruction; displaying, on the first display screen and the second display screen respectively in a full screen display manner, a preview image acquired by the rear camera; displaying, on the second display screen, pre-stored composition reference information; determining target composition information in the composition reference information; and controlling the rear camera to perform a photographing operation, based on the target composition information.
